    Maize dwarf mosaic (MDM) is a virus disease of maize (Zea mays L.) that causes yield reductions. The objective of this study was to determine yield losses caused by maized warm fosaic virus strain A (MDMV-A) in susceptible maize hybrids grown over a wide range of environmental conditions.

Maize dwarf mosaic of maize in the United States is caused by either of two major viruses: Maize dwarf mosaic virus (MDMV), or Sugarcane mosaic virus (SCMV). This is one of the most widely distributed and important corn virus diseases in the U.S.

It has been reported in 37 states located in most regions of the country, including Hawaii. Maize dwarf mosaic virus (MDMV) is the most serious virus disease of sweet corn in the USA, and production of sweet corn has been Maize dwarf mosaic virus in corn hybrids book in areas where the virus overwinters.

The virus does not overwinter in the northern tier of states but may cause serious losses in late-planted corn in this region. Notes on Taxonomy and Nomenclature Top of page Ina new maize disease was recognized in Iowa, USA (Janson and Ellett, ), and soon after was shown to be caused by a new virus named Maize dwarf mosaic virus Maize dwarf mosaic virus in corn hybrids book (Janson et al., ; Williams and Alexander, ).

MacKenzie et al. () showed that MDMV was comprised of two different strains, strain A infectious to Johnson grass. The Maize dwarf mosaic virus ImmunoStrip® is an on-site tool to quickly detect the presence of MDMV in corn and other gramineous crops.

Maize dwarf mosaic virus is a potyvirus that naturally infects members of the Poaceae (grass) family, such as corn, sorghum and Johnson grass. It is transmitted by corn seed and by a broad range of aphids in a. There are two important aphids that infest sorghum. The corn aphid Rhopalosiphum maidis is an important pest in sorghum and colonizes in large numbers inside leaf whorls, on the upper side of leaves, on the leaf sheath, and on earheads.R.

maidis is a vector for maize dwarf mosaic virus. The sugarcane aphid Melanaphis sacchari usually sucks sap from the underside of the lower leaves (Fig. Maize dwarf mosaic virus is known by various names including European maize mosaic virus, Indian maize mosaic virus and sorghum red stripe virus.

Symptoms of Dwarf Mosaic Virus in Corn. Plants with maize dwarf mosaic virus typically display small, discolored specks followed by yellow or pale green stripes or streaks running along the veins of.

Aphid transmitted maize dwarf mosaic potyvirus (MDMV): Maize dwarf mosaic is one of the most important widely distributed virus diseases of corn (Zea mays L.) in the temperate regions of the world and is especially a concern to seed producers.

It is found in. Corn for Resistance to Maize Dwarf Mosaic Virus C. Kuhn and T. Smith Department of Plant Pathology and Plant Genetics, University of Georgia, Athens, GA The research was supported in part by CSRS-ARS Research Agreement No. Although many grasses are infected by this strain of the virus, the principal overwintering reservoir host is johnsongrass.

Most outbreaks of maize dwarf mosaic in corn can be traced to nearby johnsongrass. MANAGEMENT. Use resistant hybrids to prevent the development of this disease.

Maize dwarf mosaic virus (MDMV) is a serious maize pathogen, epidemic worldwide, and one of the most common virus diseases for monocotyledonous plants, causing up to 70% loss in corn yield. Tabular data on the yields and virus disease ratings of 36 double-cross maize hybrids and 36 single-cross hybrids show that the hybrids differed widely in yield.

In general, the double-cross hybrids which produced the highest yields were the ones which had the lowest disease ratings. Similarly the single-cross hybrids with the highest yields were generally composed of inbreds which had Maize dwarf mosaic virus in corn hybrids book J.

The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or Maize dwarf mosaic virus in corn hybrids book, which are : Poaceae. Maize dwarf mosaic virus (MDMV) strain A or B Symptoms: Early infection results in chlorotic spots or flecks that elongate in young leaves in the whorl.

Flecks merge into chlorotic streaks along the leaves. These streaks form mosaic or mottled patterns and may turn to a general yellowing as the growing season progresses. Mosaic symptoms in a plant of Zea mays (sweet corn) infected with maize dwarf mosaic virus strain A.

Figure 2. Mosaic symptoms in a leaf of Zea mays (Pfisters PAG SX60 hybrid) infected by maize dwarf mosaic virus strain A (right) compared with a healthy leaf (left). Figure 3. The effects of strain A of maize dwarf mosaic virus (MDMV-A) and strain MDMV-B of sugarcane mosaic virus (SCMV-MB) on resistant sweet corn hybrids were evaluated.

Incidence of symptomatic plants, types of symptomatic responses, yield, and ear quality were. Pests & Diseases The corn leaf aphid, a bluish-green or black pest with black legs, feeds on certain varieties of sweet ation results in stunted and misshapen tassels, black mold on leaves and silk, and poor pollination.

These destructive aphids also carry maize dwarf mosaic virus. Cutworm larvae feed on leaves after dark, causing major damage to plants and often cutting of. Maize, Zea mays, is an annual grass in the family Poaceae and is a staple food crop grown all over the maize plant possesses a simple stem of nodes and internodes.

A pair of large leaves extend off of each internode and the leaves total 8–21 per plant. The Empower MZ umbrella brand signifies that in order to be used on Maizex corn hybrids or soybean varieties, the seed treatment and enhancement products have been tested by Maizex to fit the needs of our customers and provide agronomic and economic benefits versus the.

The gene action of 2 sugarcane mosaic virus (SCMV) resistance loci in maize, Scmv1 and Scmv2, was evaluated for potyvirus resistance in an isogenic 4 homozygous and 5 heterozygous isogenic genotypes were produced for introgressions of the resistant donor (FAPA) alleles at both loci into the susceptible parent (F7) genetic background using simple sequence repeat by: MDMV - Maize dwarf mosaic virus.

Transgenic maize plants expressing sugarcane mosaic virus-MDB (former MDMV-B) coat protein were also resistant to MDMV-A (Murry et al., ). The most important control measure is breeding sorghum resistant to MDMV.

Reaction of sorghum genotypes to MDMV infection markedly differ (Fazli et al., ). Maize dwarf mosaic virus (MDMV) was first reported in the state in and, at that time, was a serious problem for both field and sweet corn.

Today, most field corn hybrids are resistant or tolerant to MDMV, and the genes responsible for resistance in field corn have been transferred into sweet corn progenies. Antiserum to lettuce necrotic yellows virus did not react with maize mosaic virus in crude maize sap.
